can be rewritten as the equation of a circle, as follows.

(x-3)^2 + (y+2)^2 -9 -4 +2 = 0

(x-3)^2 + (y+2)^2 = 11

The center of the circle is (3,-2) and the radius is sqrt(11).

The other equation can be rewritten

(x+4)^2 + (y+1)^2 = 22 -17 = 5

Its center is at (-4,-1) and the radius is sqrt5

It looks to me like the two curves never intersect; I don't see how they can meet the definition of orthogonal.
